Abstract: For ascertaining the linear dichroism of a material when subjected to an electric, magnetic, hydrodynamic or acoustic force field, the invention proposes applying such a field to a sample of the material in a cell coincident with a beam of monochromatic and parallel light of predetermined wavelength and obtaining a signal representing such dichroism (referred to in the specification as ''''longitudinal dichroism'''') from a photoelectric cell, photomultiplier or other photo-detector, whereby polarisation of the light is made unnecessary. A particular form of sample cell, defined by a series array of a plurality of individual cells or compartments, each having means for applying a said force field, is also disclosed. The apparatus is contemplated not only for laboratory testing but also (using a flow cell) for ''''on line'''' applications, for controlling a parameter of a manufacturing plant or other quality control purposes.
